Description_x000D_ Application_x000D_ Cytochrome P450 is a heterogeneous family of isozymes whose primary function is to oxidize small molecules both as a function of intermediary metabolism (e.g., fatty acids) and to detoxify exogenous compounds (drugs or toxins). Alterations in the renal formation of Cytochrome P450 metabolites from arachidonic acid may participate in the formation of hypertension. Therefore, they have been identified as candidate mediators in the development of this multifactorial disease._x000D_ Biochem/physiol Actions_x000D_ Cytochrome P450 is a heterogeneous family of isozymes whose primary function is to oxidize small molecules, both as a function of intermediary metabolism (e.g., fatty acids) and to detoxify exogenous compounds (drugs or toxins). Some isoforms have narrow substrate specificity, while others are promiscuous._x000D_ Analysis Note_x000D_ Cytochrome c Reductase, b5, P450 content and p-Nitrophenol Hydroxylase activity reported on a lot-specific basis.
